Psalms 27:9

“I will say unto God my rock, etc.] A name frequently given to the eternal God, Father, Son, and Spirit, (<053204>Deuteronomy 32:4,31 <461004>1 Corinthians 10:4) (<102302>2 Samuel 23:2,3); (see Gill on “<191802>Psalm 18:2”); why hast thou forgotten me? (see Gill on “<191301>Psalm 13:1”); why go I mourning because of the oppression of the enemy? meaning perhaps Saul; though it may be applied to any spiritual enemy, sin, Satan, and the world; who are very oppressive and afflicting, and occasion continual mourning to the children of God.”

“Hide not, &c.-- (Psa 4:6; Psa 22:24). Against rejection he pleads former mercy and love.”

“Hide not thy face far from me - Compare the notes at Psalms 4:6. To “hide the face” is to turn it away with displeasure, as if we would not look on one who has offended us. The favor of God is often expressed by “lifting the light of his countenance” upon anyone - looking complacently or “pleasedly” upon him. The reverse of this is expressed by hiding the face, or by turning it away. The word “far” introduced by the translators does not aid the sense of the passage. Put not thy servant away in anger - Do not turn me off, or put me away in displeasure. We turn one away, or do not admit him into our presence, with whom we are displeased. The psalmist prayed that he might have free access to…”

“Away - From thy face or presence, or from the place of thy worship. Psalms 27:11”

“Hide: Psa 13:1, Psa 44:24, Psa 69:17, Psa 102:2, Psa 143:7; Isa 59:2 put: Psa 51:11; Isa 50:1 thou: Psa 71:5, Psa 71:6, Psa 71:17, Psa 71:18; Sa1 7:12; Isa 46:3, Isa 46:4; Co2 1:9, Co2 1:10; Ti2 4:17, Ti2 4:18 leave: Psa 38:21, Psa 119:121; Ch1 28:9; Jer 32:40; Heb 13:5 O God: Psa 24:5, Psa 38:21, Psa 38:22, Psa 88:1 Psalms 27:10”

“The requests are now poured forth with all the greater freedom and importunity, that God may be willing to be entreated and invoked. The Hiph. הטּה signifies in this passage standing by itself (cf. Job 24:4): to push aside. The clause עזרתי היית does not say: be Thou my help (which is impossible on syntactical grounds), nor is it to be taken relatively: Thou who wast my help (for which there is no ground in what precedes); but on the contrary the praet. gives the ground of the request that follows "Thou art my help (lit., Thou has become, or hast ever been) - cast me, then, not away," and it is, moreover, accented accordingly. Psa 27:10, as we have already observed, does not sound as though…”
